Description

Technical Field

[0001] The invention belongs to the field of photovoltaics, and in particular relates to a feeding system for a layered preparation type photovoltaic component frame. Background Art

[0002] Photovoltaic modules are made of crystalline silicon cells, tempered glass and packaging materials stacked in different orders, laminated to form a laminate and wrapped with a frame for protection. For a single photovoltaic module, the frame is generally made of four frames with the same cross-sectional shape, spliced ​​end to end, and combined with Figure 1 As shown, the cross section of each frame strip t' includes a long side t1', a short side t2', a connecting side t3', and a layer separation side t4', wherein the long side t1' and the short side t2' are parallel and aligned on one side, the connecting side t3' is vertically arranged with the long side t1' and the short side t2' from the aligned side, and the layer separation side t4' is located in the edge-wrapped area formed by the long side t1', the short side t2' and the connecting side t3'. When the frame strip t' is assembled, the long side t1' and the short side t2' are respectively attached to the front and back sides of the photovoltaic module, the connecting side t3' constitutes the outer end surface of the photovoltaic module, and the layer separation side t4' is located in the edge-wrapped area formed by the long side t1', the short side t2' and the connecting side t3'. t4′ separates and stacks the laminated parts; when stacked in layers, each layer has two groups of frame bars, one group of frame bars is arranged side by side with the connecting side t3′ as the bottom surface, and the two adjacent frame bars t′ are attached from the long side t1′ and the short side t2′, and the opening of the edging area faces upward; the other group of frame bars is arranged side by side with the connecting side t3′ as the bottom surface, and the two adjacent frame bars t′ are attached from the long side t1′ and the short side t2′, and the opening of the edging area faces downward. When the two groups of frame bars are stacked, the edging areas are matched up and down to form a plurality of spliced ​​rectangular bodies, and a plurality of rectangular bodies are arranged side by side in each layer, and the multiple layers are stacked in sequence.

[0003] However, photovoltaic modules are basically in the shape of a cuboid, and the frame bars formed not only have different lengths, but also have different assembly directions for the corresponding sides. Therefore, each photovoltaic module assembly requires four frame bars (two long and two short), and the two frame bars on the opposite sides need to be symmetrically arranged. This brings the following defects to the loading of the frame bars:

[0004] 1) Each time, two long frame strips are taken out from the frame strip stacking area for transfer and feeding, and then two short frame strips are taken out for transfer and feeding. Although it seems feasible on the surface, the two long frame strips and the two short frame strips are in the same direction. Since the frame strips themselves are long (generally about 3m), it is very difficult to change direction after loading, which brings great inconvenience to the actual assembly;

[0005] 2) If the corresponding frame strips are taken out one by one and combined with the multi-axis flipping of the robot, although the orientation problem can be solved, the efficiency of loading is too low to meet the assembly requirements;

[0006] 3) Regardless of whether the material-retrieving method involved in 1) or 2) is adopted, there is a great disadvantage, that is, the adjacent frame bars may be shifted during the material-retrieving process, resulting in confusion of the frame bars in the stacking area, and even the possibility of instantaneous collapse of the stacking frame bars, which greatly increases the difficulty of loading the frame bars. Summary of the invention

[0007] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a new feeding system for a layered preparation type photovoltaic component frame.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] A feeding system for a layered preparation type photovoltaic module frame, comprising:

[0010] A layered material preparation unit, comprising a plurality of material preparation groups arranged in layers from top to bottom, a transfer robot that takes out a plurality of frame strips with the same orientation from the stacking area in layers and delivers them to each material preparation group using the connecting side edges of the frame strips as the mounting surface, wherein there are at least four material preparation groups, each material preparation group has a feeding end, a discharging end and a transmission surface, the edge-wrapped area openings of each frame strip are all facing upwards and are stored on the transmission surface from the mounting surface, each transmission surface transmits the frame strips from the back to the front, and the plurality of transmission surfaces are divided into two groups, wherein the mounted frame strips are mounted side by side with the long side in front and the short side in the back to form a first material preparation group, and the mounted frame strips are mounted side by side with the short side in front and the long side in the back to form a second material preparation group;

[0011] A material placement unit, comprising a material placement rack located below the material discharging end, and a plurality of material placement modules formed on the material placement rack and arranged side by side along the front-to-back direction, wherein each material placement module forms a material placement trough with an opening facing upward, and the plurality of material placement modules are divided into a first material placement group and a second material placement group corresponding to the first material preparation group and the second material preparation group;

[0012] The material picking unit includes a material distributor formed at the discharge end of each material preparation group for single frame strip distribution, a material picking joint, and a power device for driving the material picking joint to rise and fall, wherein the material picking joint and the material placing module are relatively staggered and avoided, and each material picking joint is formed with a bearing groove with an upward opening, the bearing groove is similar to the material placing groove, and the bearing groove takes the front side as a reference, and the single frame strip separated by the material distributor gradually slides forward along the reference and gradually separates from the discharge end and is unloaded to the bearing groove; the frame strips placed in each bearing groove keep the angle formed by the connecting side and the horizontal plane equal, and the long and short sides are respectively located at the upper and lower ends of the connecting side; as the bearing groove descends, the placed frame strips are unloaded to the corresponding material placing module, and the frame strips in the first material placing group and the second material placing group are symmetrically distributed.

[0013] Preferably, the material placement groove and the bearing groove are both V-shaped grooves with openings facing upwards. Based on the layout of the inclined V-shaped grooves, the frame strips are fed at the same inclined angle to facilitate subsequent assembly implementation.

[0014] According to a specific implementation and preferred aspect of the present invention, the V-shaped groove is in a right-angle shape, so that it can match the right-angle side corresponding to the frame strip, thereby increasing the stability and safety of the frame strip feeding.

[0015] In some specific embodiments, the material preparation group includes an annular conveyor belt, and when taking materials, the rear side of the V-shaped groove is kept tangent to the discharge end. Through the tangent matching position relationship, it is more stable during the unloading of the frame strips, especially for the frame strips with the long side in front and the short side in the back, it is difficult to achieve the movement connection of the frame strips due to the center of gravity and inertial movement. However, based on the tilt angle and the length of the support formed, the present application adopts a tangent and transmission-influencing method to smoothly tilt and unload the frame strips to the corresponding V-shaped grooves.

[0016] According to another specific implementation and preferred aspect of the present invention, in the orthographic projection along the length direction of the frame strip, the V-shaped groove is composed of a first groove wall and a second groove wall distributed front and back, wherein the frame strip is attached to the second groove wall from the connecting side and emerges from the second groove wall, and the frame strip is attached to the first groove wall from the long side or the short side. The shapes of the V-shaped groove and the frame strip are matched to facilitate the transfer of the frame strip.

[0017] In some specific embodiments, the angle formed by the second groove wall and the horizontal plane is ∠1, where ∠1≤30°; at the same time, in the orthographic projection along the length direction of the frame bar, the length of the connecting side of the frame bar is L1, the length of the second groove wall is L2, the length of the first groove wall is L3, and the length of the short side of the frame bar is L4, where L1>L2>L3≥L4. This is to avoid movement connection accidents, that is, to avoid the frame bar rolling off from the V-shaped groove.

[0018] According to another specific implementation and preferred aspect of the present invention, each photovoltaic module frame has four frame bars, which are divided into two long and two short ones; there are four stock preparation groups, and the four stock preparation groups are arranged in order from top to bottom according to long frame bars, short frame bars, short frame bars, and long frame bars, wherein the long frame bars and short frame bars at the top constitute the first stock preparation group, and the short frame bars and long frame bars at the bottom constitute the second stock preparation group. That is, the feeding system takes one photovoltaic module as the feeding base, in other words, four frame bars, two long and two short, need to be provided each time.

[0019] Preferably, the feed ends of the four material preparation groups are aligned; the discharge ends of the four material preparation groups are gradually protruding from bottom to top, and there are four material placement troughs corresponding to the discharge ends of each material preparation group. This layout of the feed end and the discharge end is not only convenient for adding frame strips to each layer of the material preparation group, but also based on the length difference, it is convenient to implement the connection and transfer of the material taking joints in a smaller space.

[0020] According to another specific implementation and preferred aspect of the present invention, there are two groups of material taking joints, one group is used for synchronous transfer of long and short frame strips of the first material preparation group; the other group is used for synchronous transfer of short and long frame strips of the second material preparation group. That is, not only the time required for transferring the frame strips is shortened, but also the frame strips with the same direction are kept to be transferred synchronously.

[0021] Preferably, each material taking joint group has at least two material taking joints, and each material taking joint includes an upper material taking module and a lower material taking module installed on the same base body and having a height difference, the bearing slots are respectively located on the upper material taking module and the lower material taking module, and the height difference between the upper material taking module and the lower material taking module is equal to the height difference between the upper and lower material preparation groups. After the tangent position is aligned by equal height difference, the four frame bars can be unloaded at the same time, greatly improving the feeding efficiency.

[0022] Further, there are two corresponding power devices, and each power device is used to drive the corresponding seat body to move up and down to perform a group of long and short frame strips with the same direction to be transferred synchronously. In short, the two power devices can be synchronized or sequentially, depending on actual needs.

[0023] According to another specific implementation and preferred aspect of the present invention, the material distributor includes a first module and a second module located above the transmission path, wherein the first module and the second module are both capable of blocking and releasing the forward movement of the frame strips, and the frame strips are gradually prepared in a switching movement in which one of the first module and the second module is in a blocking position and the other is in a releasing position. By switching the blocking and releasing positions and coordinating the movement of the endless conveyor belt, the frame strips can be unloaded one by one into the connected bearing slots.

[0024] Specifically, the first module and the second module are arranged front and back, wherein the first module includes blocking modules located at both ends, and first telescopic cylinders that drive the blocking modules to move along the length direction of the frame strip, wherein the two first telescopic cylinders are telescopic so that the two blocking modules form end blocking and release; the second module includes clamping modules located at both ends, and second telescopic cylinders that drive the clamping modules to move along the length direction of the frame strip, wherein the two second telescopic cylinders are telescopic so that the two clamping modules form end clamping and release. In short, the frame strips arranged side by side are transmitted forward, and the first, second, third...Nth ones are sequentially, and the blocking module first forms a block (with the long side or short side of the front side of the frame strip as the positioning reference), the first, second, third...Nth frame strips slip relative to the circular conveyor belt, and then the clamping module moves to clamp the second frame strip, and the clamping module makes the second, third...Nth frame strips slip relative to the circular conveyor belt, then the blocking module retracts to form a release, and the first frame strip is unloaded to the connected bearing slot along with the circular conveyor belt, and finally, the frame strip automatically fills the position, and the above actions are repeated to complete the loading of the frame strip.

[0025] According to another specific implementation and preferred aspect of the present invention, a plurality of support modules are arranged at intervals at the discharge end, wherein each support module comprises a mounting portion, a horizontal support portion, and a guide portion extending downward and forward from the front end of the horizontal support portion, wherein the top surface of the horizontal support portion is flush with the transmission surface of the corresponding discharge end, and the angle formed between the top surface of the guide portion and the top surface of the horizontal support portion is equal to the inclination angle of the connecting side after mounting. The horizontal support portion is used for support so that the frame strip is unloaded more smoothly, and at the same time, under the inclined guidance and the contact deceleration formed, the frame strip slowly falls into the bearing groove, avoiding the probability of the frame strip accidentally rolling down due to the excessive unloading speed.

[0026] In some specific embodiments, each material preparation group includes a plurality of circular conveyor belts spaced side by side, an end alignment module and a fence calibration module located at relatively outer sides of the plurality of circular conveyor belts, wherein the end alignment module includes an alignment template located at both ends of the frame bar and capable of relative movement along the length direction of the frame bar, and an alignment driver corresponding one to one to the alignment template; the fence calibration module includes a fence template forming an input and output port, wherein the material divider is located at the front side of the output port.

[0027] Specifically, there are two annular transmission belts (of course it can be 3, 4, 5, 6 or more), and the gate template is arranged based on the length of the frame strip, and an entry port and an exit port are formed at both ends, that is, the ends of the frame strips entering between the two gate templates are in a relatively aligned (relatively corrected position) forward transmission; the alignment template is located at the entry port, and the frame strips are aligned during relative motion to avoid jamming or blocking of the frame strips entering the entry port due to incorrect position.

[0028] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0029] Based on the feeding of existing frame bars, no matter whether two are taken at a time or only one is taken each time, for the frame assembly of a single photovoltaic module, there are not only differences in long and short sides, up and down, but also in direction. Therefore, if the above method is used for feeding, not only the feeding efficiency cannot meet the assembly needs, but also due to the stacking characteristics of the frame bars themselves, adjacent frame bars may be shifted during the material taking process, resulting in confusion of the frame bars in the stacking area, and even the possibility of instantaneous collapse of the stacking frame bars, which greatly increases the difficulty of loading the frame bars, etc. The present invention cleverly solves the various deficiencies of the existing structure by overall design of the feeding system of the layered preparation type photovoltaic module frame. After adopting the feeding system, first, multiple frame strips are prepared, wherein the prepared materials are divided into two groups, and are arranged side by side with the long side in front and the short side in the back or with the short side in front and the long side in the back; then, the frame strips from each preparation group are gradually slid down along the reference and gradually separated from the discharge end and unloaded to the bearing groove, wherein the frame strips placed in each bearing groove keep the angle formed by the connecting side and the horizontal plane equal, and the long and short sides are respectively located at the upper and lower ends of the connecting side; finally, the frame strips placed as the bearing groove descends are unloaded to the corresponding loading module, and the frame strips in the first loading group and the second loading group are symmetrically distributed to complete the assembly and feeding of a single photovoltaic module frame. Therefore, on the one hand, the present invention adopts a layered preparation method for frame bars, and based on the opening orientation of the layered frame bars, the front-to-back distribution of the short sides, and the equal-angle bearing formed by the bearing grooves, two groups of frame bars are kept in symmetrical angles and orientations to carry out a single feeding of the photovoltaic module frame, thereby meeting the gluing and assembly implementation requirements of the frame bars under the premise of symmetry, and at the same time, through the guidance and deceleration formed by the reference, the probability of accidental rolling of the frame bars due to excessive unloading speed is avoided; on the other hand, the method for taking the frame bars is also to take out multiple frame bars with the same orientation in layers from the stacking area. Therefore, the probability of frame bar displacement and confusion is low, which is more conducive to the replenishment of frame bars. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] like Figures 2 to 10As shown, the feeding system of the layered preparation type photovoltaic module frame of this embodiment includes a layered preparation unit ①, a placing unit ②, and a taking unit ③.

[0048] Specifically, the layered material preparation unit ① takes a single photovoltaic module frame as an example to supply long frame strips and short frame strips in layers. In this example, the layered material preparation unit ① includes four material preparation groups 1 arranged in layers from top to bottom, and a transfer robot 2 that takes out multiple frame strips t with the same orientation from the stacking area and delivers them to each material preparation group 1 using the connecting side t3 of the frame strip t as the mounting surface.

[0049] In some specific embodiments, each preparation group 1 has a feed end 1a, a discharge end 1b and a transmission surface 1c, and the edge area openings of each frame strip t are all stored on the transmission surface 1c from the mounting surface facing upward, and each transmission surface 1c transmits the frame strip t from back to front. The four preparation groups 1 are arranged in order from top to bottom according to long frame strips, short frame strips, short frame strips, and long frame strips, wherein the long frame strips and short frame strips at the top constitute the first preparation group 11, and the short frame strips and long frame strips at the bottom constitute the second preparation group 12. That is, the feeding system takes one photovoltaic module as the feeding base, in other words, four frame strips, two long and two short, need to be provided each time. In short, the mounted frame strips are arranged side by side with the long side in front and the short side in the back to form the first material preparation group 11, and the mounted frame strips are arranged side by side with the short side in front and the long side in the back to form the second material preparation group 12. That is to say, from top to bottom, the first material preparation group 11 is composed of long frame strips and short frame strips with the same orientation and the same front and back distribution of long and short sides; the first material preparation group 12 is composed of short frame strips and long frame strips with the same orientation and the same front and back distribution of long and short sides.

[0050] In this example, the feeding ends 1a of the four material preparation groups 1 are aligned; the discharging ends 1b of the four material preparation groups 1 are gradually protruding from bottom to top. At the same time, the transfer robot 2 is based on the premise of layered clamping frame strips, combined with a multi-axis motion method, to keep the connecting side t3 facing downward to supplement the frame strips t of each material preparation group 1.

[0051] Furthermore, each material preparation group 1 includes a plurality of annular conveyor belts 10 that are spaced side by side, an end alignment module 13 and a fence calibration module 14 that are located on the relatively outer sides of the plurality of annular conveyor belts 10, wherein the end alignment module 13 includes an alignment template 130 that is located at both ends of the frame bar and can move relative to the length direction of the frame bar, and an alignment driver 131 that corresponds one to one with the alignment template 130; the fence calibration module 14 includes a fence template 140 that forms an entry and exit port. Specifically, there are two annular conveyor belts 10 (of course, it can be 3, 4, 5, 6 or more), and the fence template 140 is arranged based on the length of the frame bar, and an entry and exit port are formed at both ends, that is, the end of the frame bar entering between the two fence templates 140 is in a relatively aligned (relatively corrected position) forward transmission; the alignment template 130 is located at the entry and entry port, and aligns the frame bar during relative movement to avoid the phenomenon of material jamming or blocking due to incorrect position of the frame bar entering the entry and entry port.

[0052] The loading unit ② includes a loading rack 3 located below the discharge end 1b, and four loading modules 4 formed on the loading rack 3 and arranged side by side along the front-to-back direction, wherein each loading module 4 forms a loading trough 40 with an opening facing upward, and the four loading modules 4 are divided into a first loading group 41 and a second loading group 42 corresponding to the first preparation group 11 and the second preparation group 12, and the four loading troughs 40 correspond to the discharge end 1b of each preparation group 1 respectively.

[0053] The material picking unit ③ includes a distributor 5 formed at the discharge end 1b of each preparation group 1 for single frame strip distribution, a material picking joint 6, and a power device 7 for driving the material picking joint 6 to rise and fall, wherein the material picking joint 6 and the material placing module 4 are relatively staggered and avoided, and each material picking joint 6 is formed with a bearing groove 60 with an opening facing upward, the bearing groove 60 is similar to the material placing groove 40, and the bearing groove 60 is used as a reference on the front side, and the single frame strip separated by the distributor 5 gradually slides forward along the reference and gradually separates from the discharge end 1b and is unloaded to the bearing groove 60; the frame strips placed in each bearing groove 60 maintain an equal angle between the connecting side and the horizontal plane, and the long and short sides are respectively located at the upper and lower ends of the connecting side; at the same time, as the bearing groove 60 descends, the placed frame strips are unloaded to the corresponding material placing module 4, and the frame strips in the first material placing group 41 and the second material placing group 42 are symmetrically distributed.

[0054] In some specific embodiments, the distributor 5 includes a first module 51 and a second module 52 located above the transmission path, wherein the first module 51 and the second module 52 can both block and release the forward movement of the frame strip, and the frame strip is gradually prepared in the switching movement in which one of the first module 51 and the second module 52 is in blocking and the other is in releasing. By switching the blocking and releasing positions and coordinating the movement of the annular conveyor belt, the frame strips can be unloaded one by one into the connected bearing grooves. Specifically, the first module 51 and the second module 52 are arranged front and back, wherein the first module 51 includes blocking modules 510 located at both ends, and first telescopic cylinders 511 that respectively drive the blocking modules 510 to move along the length direction of the frame strip, wherein the two first telescopic cylinders 511 are telescopic so that the two blocking modules 510 form end blocking and release; the second module 52 includes clamping modules 520 located at both ends, and second telescopic cylinders 521 that respectively drive the clamping modules 520 to move along the length direction of the frame strip, wherein the two second telescopic cylinders 521 are telescopic so that the two clamping modules 520 form end clamping and release. In short, the side-by-side frame strips are transmitted forward, and in turn, the 1st, 2nd, 3rd...Nth frame strips are first blocked by the blocking module (with the long side t1 or the short side t2 of the front side of the frame strip as the positioning reference), and the 1st, 2nd, 3rd...Nth frame strips slip relative to the circular conveyor belt. Then, the clamping module 520 moves to clamp the layer separation edge t4 of the second frame strip t, and the clamping module 520 causes the 2nd, 3rd...Nth frame strips to slip relative to the circular conveyor belt. Then, the blocking module retracts to form a release, and the 1st frame strip is unloaded with the circular conveyor belt to the connected load-bearing slot. Finally, the frame strip automatically fills the position, and the above actions are repeated to complete the loading of the frame strips.

[0055] In some specific embodiments, there are two groups of material-collecting connectors 6, one group is used for the synchronous transfer of long and short frame strips of the first material preparation group 11; the other group is used for the synchronous transfer of short and long frame strips of the second material preparation group 12. That is, not only the time required for the transfer of frame strips is shortened, but also the frame strips in the same direction are kept to be transferred synchronously. In this example, each material-collecting connector group has two material-collecting connectors 6, wherein the two material-collecting connectors 6 are distributed corresponding to the annular conveyor belt 10, and each material-collecting connector 6 includes an upper material-collecting module 61 and a lower material-collecting module 62 installed on the same seat body and having a height difference, and the bearing groove 60 is respectively located on the upper material-collecting module 61 and the lower material-collecting module 62, and the height difference between the upper material-collecting module 61 and the lower material-collecting module 62 is equal to the height difference between the upper and lower material preparation groups 1. After the tangent position is aligned by equal height difference, the four frame strips can be unloaded at the same time, which greatly improves the feeding efficiency. There are two corresponding power devices 7, and each power device 7 is used to drive the corresponding seat body to move up and down to carry out a group of long and short frame strips with the same direction to be transferred synchronously. In short, the two power devices 7 can be synchronous or sequential, depending on actual needs.

[0056] In addition, the material placement groove 40 and the bearing groove 60 are both V-shaped grooves with the opening facing upward. Based on the layout of the inclined V-shaped grooves, the frame strips are fed at the same inclination angle to facilitate the subsequent assembly implementation. The V-shaped groove is in a right angle, so that it can match the right-angle side corresponding to the frame strip, increase the stability and safety of the frame strip feeding, and at the same time, when taking the material, the rear side of the V-shaped groove remains tangent to the discharge end. Through the tangential matching positional relationship, it is more stable during the unloading of the frame strips, especially for the frame strips with the long side in front and the short side in the back. Due to the center of gravity and inertial movement, it is difficult to achieve the movement connection of the frame strips. The present application is based on the inclination angle and the length of the support formed, and adopts a tangent and transmission-free method to smoothly unload the frame strips to the corresponding V-shaped grooves.

[0057] In this example, in the orthographic projection along the length direction of the frame strip t2, the V-shaped groove is composed of the first groove wall c1 and the second groove wall c2 distributed front and back, wherein the frame strip is attached to the second groove wall c2 from the connecting side and emerges from the second groove wall c2, and the frame strip is attached to the first groove wall c1 from the long side t1 or the short side t2. The V-shaped groove and the shape of the frame strip t are matched to facilitate the transfer of the frame strip t. The angle formed by the second groove wall c2 and the horizontal plane is ∠1, wherein ∠1≤30° (∠1=27° in this example); at the same time, in the orthographic projection along the length direction of the frame strip t, the length of the connecting side t3 of the frame strip is L1, the length of the second groove wall c2 is L2, the length of the first groove wall c1 is L3, and the length of the short side t2 of the frame strip is L4, wherein L1>L2>L3≥L4. This is to avoid the occurrence of movement connection accidents, that is, to avoid the phenomenon of the frame strip rolling down from the V-shaped groove.

[0058] In this example, based on the long length of the long frame strip t, a support module 8 that can be aligned with the corresponding annular conveyor belt 10 is provided at the position of the discharge end 1b, wherein the support module 8 and the annular conveyor belt 10 are arranged relatively spaced apart to implement the support of the long frame strip t. In some specific embodiments, the support module 8 includes a mounting portion 80, a horizontal support portion 81, and a guide portion 82 extending downward and forward from the front end of the horizontal support portion 81, wherein the angle formed between the top surface of the guide portion 82 and the top surface of the horizontal support portion 81 is equal to the inclination angle of the connecting side t3 after mounting. In this way, a guide is formed in the translation and oblique feeding to avoid the accidental rolling of the frame strip, and for the long frame strip, it can be more stably supported and transferred. Furthermore, the support modules 8 are located in the topmost and bottommost material preparation groups 1 (because the short sides are shorter, they are less likely to bend or deform), wherein each layer has two support modules 8, and the two support modules 8 are correspondingly distributed on the outsides of the two annular conveyor belts 10 on the same layer, and the two support modules 8 and the two annular conveyor belts 10 are spaced apart along the length direction of the long frame strips (equal spacing is optimal).

[0059] In summary, the implementation process of this embodiment is as follows:

[0060] First, prepare multiple frame strips, where the prepared materials are divided into two groups, and are placed side by side in a manner of long side in front and short side in back or short side in front and long side in back. At the same time, the transfer robot takes out multiple frame strips with the same direction from the stacking area in layers for connection, and the side edges are continuously supplied by flipping the mounting surface. From top to bottom, the four layers are respectively long frame strips and short frame strips with the long side in front and the short side in back, and short frame strips and long frame strips with the short side in front and the long side in back. At the same time, the opening directions of all frame strips are the same (all facing upwards).

[0061] Secondly, the front side of the load-bearing groove is used as a reference, and the single frame strip separated by the distributor gradually slides forward along the reference and gradually separates from the discharge end to be unloaded into the load-bearing groove, wherein the frame strips placed in each load-bearing groove keep the angle formed by the connecting side and the horizontal plane equal, and the long and short sides are respectively located at the upper and lower ends of the connecting side;

[0062] Finally, based on the descent of the bearing slot, the frame strips are unloaded to the corresponding material placement module while maintaining the original angle and position, and the frame strips in the first material placement group and the second material placement group are symmetrically distributed to complete the assembly and feeding of a single photovoltaic module frame.

[0063] In summary, the present invention adopts a layered preparation method for frame strips on the one hand, and based on the opening orientation of the layered frame strips, the front-to-back distribution of the short sides, and the equal angle bearing formed by the bearing grooves, the two groups of frame strips are kept at symmetrical angles and orientations to feed a single photovoltaic module frame at one time, thereby meeting the gluing and assembly implementation requirements of the frame strips under the premise of symmetry, and at the same time, through the guidance and deceleration formed by the reference, the probability of accidental rolling of the frame strips due to excessive unloading speed is avoided; on the other hand, the frame strip picking method is also to pick up multiple frame strips with the same orientation in layers from the stacking area, so the frame strip displacement occurs. , the probability of confusion is low, which is more conducive to the replenishment of the frame strips; the third aspect is based on the layout of the inclined V-groove, so that the frame strips maintain the same inclination angle for feeding, so as to facilitate the subsequent assembly implementation, and at the same time, the V-groove is in a right angle, so that it can match the right-angle side corresponding to the frame strip, thereby increasing the stability and safety of the frame strip feeding. In addition, when taking the material, the tangential matching position relationship makes it more stable during the unloading of the frame strips, especially for the frame strips with the long side in front and the short side in the back. Due to the center of gravity and inertial movement, it is difficult to achieve the movement connection of the frame strips, and the present application is based on the inclination angle, the support length formed The frame strips are short, and are smoothly unloaded to the corresponding V-shaped grooves in an inclined manner without affecting the transmission by means of being tangent; the fourth aspect is based on the layout of the feed end and the discharge end, which is not only convenient for adding frame strips to each layer of the material preparation group, but also based on the difference in the length direction, it is convenient to implement the connection and transfer of the material taking joints in a smaller space. At the same time, two material taking joints are used and the height difference is utilized to synchronously unload the frame strips of the first material preparation group and the second material preparation group one by one. In addition, based on the switching of the blocking and releasing positions of the first module and the second module, and in coordination with the movement of the annular conveyor belt, the frame strips can be unloaded one by one into the connected load-bearing grooves; the The fifth aspect is to align the ends of the frame strips to avoid jamming or blocking of the frame strips entering the inlet and outlet ports due to incorrect positioning. At the same time, the fence template is arranged based on the length of the frame strips, and an inlet and outlet port are formed at both ends, that is, the ends of the frame strips entering between the two fence templates are in a relatively aligned (relatively corrected position) forward transmission; the sixth aspect is to support the frame strips through the horizontal support part to make the unloading of the frame strips smoother. At the same time, under the inclined guidance and the contact deceleration formed, the frame strips slowly fall into the receiving grooves to avoid the probability of accidental rolling of the frame strips due to excessive unloading speed.
